The simulation results show that the algorithm based on expectation prediction value achieves higher prediction hit rate of cache and lower average waiting delay than the algorithm based on FIFO.

仿真实验结果表明，该算法与传统的FIFO算法相比较，提高了缓存的预测命中率，减少了用户平均等待延迟。

Expectation of life is the average Numbers of years that a person is expected to live. The expectancy of life is the prediction of average years a person can live.

估计寿命是预计一个人能活得平均年数。

Thirdly, it analyses prediction technology in scheduling, and proposes prediction model to predict task expected completion time using subtasks with maximum mathematical expectation.

在此基础上，建立基于数学期望的任务预期完成时间预测模型，用具有最大期望完成时间的子任务预测任务预期完成时间；

Rudniski noted that excluding those numbers, the company would have earned 39 cents per share, still over Wall Street's prediction, as well as his own 36 cent expectation.
